Agentverse MCP
Agentverse MCP Server allows you to use the Agentverse API in your MCP clients.
Heads up
Compatible with Cursor, Claude Code/Claude Desktop, OpenAI Playground, and Cline — and generally any MCP client.
Overview
The Model Context Protocol (MCP) is an open standard that lets AI systems interact with external data sources and tools over a secure, two‑way channel.
Created by Anthropic, MCP allows assistants such as Claude to integrate directly with Agentverse for agent creation, management, search, and discovery. With MCP, developers can build, deploy, and operate agents on the Agentverse marketplace—and surface them to users via ASI1 agentic LLM. ​
Features
- Agents & Hosting API: Create/update agents, upload code (JSON array), start/stop, and fetch details/logs.
- Marketplace Search API: Search and discover agents; fetch public agent profiles.
- Storage API: Get/set/delete per-agent key-value storage for lightweight state.
- Secrets API (User-level): List/create/delete user secrets available to your agents.
- Almanac API (Main MCP): Register and query agents on the on-chain Almanac (network-aware ops).
- Mailbox API (Main MCP): Manage mailboxes, quotas, and message metrics for Local/Mailbox agents.
- Service & Health (Main MCP): Health checks and transport endpoints (SSE/HTTP) for diagnostics.
Remote MCP Server
You can connect to Agentverse MCP via the following remote URLs.
There are two remote MCP servers available:
- Agentverse MCP
- Agentverse MCP Lite
MCP vs MCP Lite
- MCP Lite: Minimal server exposing the core tools to create, update, start/stop agents, and search the marketplace. Optimized for clients with tool-count limits.
- MCP (Main): Production server with the full Agentverse toolset for advanced workflows (storage, quotas, analytics, and more).

Initialization prompt and Vibe Coding rules
Download the av-mcp.mdc
file and place it in your editor’s rules folder (e.g., Cursor), or paste it as a Developer/System message in OpenAI Playground. You can also use it as the initialization prompt in Claude Desktop.
AV MCP Rules Features
- Protocol correctness: Enforces Agent Chat Protocol invariants, strict ACK rhythm, and session/stream semantics.
- Version targeting: Aligns with latest
uagents
behavior. - Scaffolds and layouts: Standard
hosted/
andmailbox_or_local/
structures with README guidance. - Hosted allowlist: Curated imports for Hosted agents; recommend Mailbox/Local when deps aren’t supported.
- Storage & media:
ExternalStorage
usage patterns; image analysis/generation; tmp URL staging for video/audio. - Rate limits & ACL:
QuotaProtocol
examples with per-sender quotas and optional ACL bypass. - MCP reliability: Create/update/start, JSON-stringified code uploads, retry guidance, raw JWT token requirement.
- Secrets policy: Hosted ignores repo

; configure secrets in Agentverse. Mailbox/Local requireAGENT_NAME
,AGENT_SEED
,PORT/AGENT_PORT
. - Templates & checklists: Ready-to-run examples and a final preflight checklist plus required README badges.
Usage example
Cursor and Vibe Coding rules
-
Create a new project in Cursor.
-
Follow the steps in Connect to Cursor to add the MCP server.
-
Add the
av-mcp.mdc
rules in Cursor using this guide: Cursor Rules. -
After saving, you should see
.cursor/rules/av-mcp.mdc
in your project. -
Use the sample API and prompt below to create a Hosted agent that calls the ASI1 API and acts as a Supercars expert.
AV API Key Needed
If prompted for an Agentverse API key during hosting, use your personal token.
- Chat with the Cursor agent and provide additional details if needed.

- You should see the agent created in Agentverse; you can chat with it immediately.

- Test the agent in ASI:One (Agentic mode) to verify it’s working end‑to‑end.

Wrap-up
You now have two ways to use Agentverse via MCP:
- Use the remote servers:
- Main:
https://mcp.agentverse.ai/sse
(full toolset for Claude/OpenAI/Cline) - Lite:
https://mcp-lite.agentverse.ai/mcp
(optimized for Cursor/Windsurf)
- Main:
- Bring the “AV MCP Rules” into your editor or assistant to generate correct agents quickly.
Next, try building a Hosted agent template and starting it from your MCP client. If you need help or run into issues:
- Visit the Hosted Agents and ASI:One Compatible Agent pages for end‑to‑end examples.
- See “Agent Logs Errors” for troubleshooting.
We’re excited to see what you build—happy agenting!
